Catalyst for synthesizing dimethylether or methylacetate from synthetic gas, method for preparing the same, and method for preparing dimethylether or methylacetate using the same

A hybrid CZA/FER catalyst comprising:

• a nanosheet ferrierite zeolite;
• and
• a Cu—Zn—Al-based oxide supported on the nanosheet ferrierite zeolite;
• wherein the nanosheet ferrierite zeolite has a shape in which one or more sheets having a thickness of about 5 nm to about 10 nm and a width of about 100 nm to about 150 nm are stacked;
• and
• wherein an amount of weak acid sites in the nanosheet ferrierite measured through NH3-TPD analysis is about 0.562 mmol/gcat to about 0.736 mmol/gcat;
• an amount of medium acid sites in the nanosheet ferrierite measured through NH3-TPD analysis is about 0.118 mmol/gcat to about 0.243 mmol/gcat;
• an amount of strong acid sites in the nanosheet ferrierite measured through NH3-TPD analysis is about 0.423 mmol/gcat to about 0.552 mmol/gcat;
• an amount of Brönsted acid sites in the nanosheet ferrierite measured through Py-IR analysis is about 0.126 mmol/gcat to about 0.266 mmol/gcat;
• an amount of Lewis acid sites in the nanosheet ferrierite measured through Py-IR analysis is about 3.130×102 mmol/gcat to about 3.962×102 mmol/gcat;
• or
• an amount of Brönsted acid sites in 8 membered-rings of the nanosheet ferrierite combined NH3-TPD and Py-IR analysis results is about 0.250 mmol/gcat to about 0.297 mmol/gcat.
